BOTTLE-FUNNEL.

SPECIFICATION forming part of Letters Patent No. 388,386, dated August 21, 1888.

Application tiled June 14, 1888. Serial No. 277.120.

To all whom it may concern:

Be it known that we, CHRISTIAN XANDER and \VILLIAM Tnoims, of Washington, in the District of Columbia, have invented certain new and useful Improvements in Bottle-Funnels; and we do hereby declare that the following is a full, clear, and exact description of the invention,whichwillenableothersskilledintheartto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to the class known as hair bottlefunnels.

It has for its object the filling of bottles and other vessels without the defect usual of the vent or escape of air interfering with the liquid as it enters the bottle.

Heretofore funnels have been made with corrugations, serrations, or indentations on their periphery, and some have been made with tubes running centrally through, and others have tubes at their sides running the entire length of the funnel; but the tube projects and interferes with the funnel setting steadily in the bottle, while the corrugations flatten and choke up. Others have been made with concentric tubes, which are objectionable as very costly, and they also lessen the capacity of the bottle to receive the liquid in its full flow, which is very essential to economy in time. \Ve are perfectly aware of all these construe tions and of their defects, and hence lay no claim to them. Therefore to avoid the defects now existing in funnels and to produce a funnel that will fully produce the best and economic results are further objects of our invention. v

To these ends our invention consists in forminga funnel of the shape ofan inverted cone,its stem or shank to be made with an indentation extending longitudinally along its side. This indentation is covered by soldering or otherwise securing an independent piece of metal over it, thus forming a tube-vent, all of which will hereinafter more fully appear.

In the drawings the same letters will indicate like parts in the several figures.

Figure 1 is a perspective view showing our complete funnel, a part being broken away to show the strainer. Fig. 2 is a vertical section (No model.)

of the funnel. Fig. 3 shows the shank of the funnel with the indentation; Fig. 4, the piece or shank that forms the vent-tube, and Fig. 5 a crosssection on the line m .r of Fig. 1.

A is the upper portion of the funnel, and B the shank.

C is the indentation formed in the shank by any well-known means, and D is the blank to cover the groove or indentation C. The blank D is formed with a toe-piece, a, which covers the bottom of the tube and prevents contact with the liquid. This blank D is also provided with escape ports or apertures for the displaced air within the bottle. The venttube is open at the top of the shank B, which portion is always outside of the neck of the bottle, so that air entering the port escapes through and from the top of the vent-tube, thus entirely escaping contact with the liquid.

A long experience has demonstrated that if liquid passes down into the vessel in contact with the escaping air the operation of filling is defective for the reason that two forces in contactarepassinginoppositedirections. This is even so ifthe air escapes near the entry ofthe fiuid into a separated tube, for in passing up it carries the fluid with it,and thus chokes the escape, and bnbblingis the result. Furthermore, it requires great care to prevent the tube from choking up with dirt, as it is well known store dust when saturated with liquid forms a scale, and thus stops up the tube.

With our invention the vent-tube is entirely independent of the liquid-conduit, so that no contact whatever takes place. Thus while the liquid is passing down the air is passing up, the air entering the ports some distance from where the liquid discharges and in this manner the liquid has free flow while the air has free escape, perfect operation being the result.

"We locate within the body of the funnel a screen, E, which has a twofold object. One is to strengthen and stay the funnel andthe other is to intercept and trap any foreign substances that may be in the liquid from entering the vessel.

It is evident several modifications ofthe contour of the tube may be made without departing from the spirit of our invention; but it must be understood that in any modification the air must enter the venttube above the discharge of the liquid and escape outside of and covering said indentation with a piece of the neck of the vessel. metal provided with air-induction apertures,

It will be readily seen that funnels of varithe top of the tube forming the exit for the i5 ous sizes may be made to suit vessels of differair, substantially as set forth.
